Females can reach a body length of 9–11 mm (0.35–0.43 in), males can reach a length of 8–9 mm (0.31–0.35 in). The female is light yellowish, with a very white cephalus and red rings surrounding the narrow black rings round the eyes. Two longitudinal bright red stripes are present on the opisthosoma. The male is very dark, with white markings, and red hairs around the eyes. They appear in Singapore, Indonesia, Pakistan, Iran, India, and Bhutan. T. dimidiata is non-venomous and produces no toxin significant to humans.
Since 1999, the spider has been the subject of an email hoax claiming that it was a fatal spider found lurking under toilet seats in North Florida. This hoax was a rehashing of an older email circulated in 1999 with similar claims, except under the name "South American Blush Spider (arachnius gluteus [sic])" - literally "butt spider". Similar email hoaxes (with details of the original changed) occurred in other parts of the world, alleging the same falsity in the recipients' countries. Lately[when?] it has also appeared on Facebook, also including a picture of the arachnid. Posts commonly report of it being found world-round, suggesting everyone must take precautions. No such events appear to have occurred, and the story is considered an urban legend. The false rumor has since spread to websites such as Twitter, Facebook and Tumblr in 2012.
